Measuring the Confidence of Traffic Forecasting Models: Techniques, Experimental Comparison and Guidelines towards Their Actionability
Ibai Laña, Ignacio, Olabarrieta +1
The estimation of the amount of uncertainty featured by predictive machine learning models has acquired a great momentum in recent years. Uncertainty estimation provides the user w…
Critical Behavior in the Gravitational Collapse of a Scalar Field with Angular Momentum in Spherical Symmetry
Ignacio Olabarrieta, Jason F. Ventrella, Matthew W. Choptuik +1
We study the critical collapse of a massless scalar field with angular momentum in spherical symmetry. In order to mimic the effects of angular momentum we perform a sum of the str…
Scalar field confinement as a model for accreting systems
Miguel Megevand, Ignacio Olabarrieta, Luis Lehner
We investigate the possibility to localize scalar field configurations as a model for black hole accretion. We analyze and resolve difficulties encountered when localizing scalar f…
Head-on collisions of boson stars
C. Palenzuela, I. Olabarrieta, L. Lehner +1
We study head-on collisions of boson stars in three dimensions. We consider evolutions of two boson stars which may differ in their phase or have opposite frequencies but are other…
Towards the Final Fate of an Unstable Black String
M. W. Choptuik, L. Lehner, I. Olabarrieta +3
Black strings, one class of higher dimensional analogues of black holes, were shown to be unstable to long wavelength perturbations by Gregory and Laflamme in 1992, via a linear an…
Critical phenomena at the threshold of black hole formation for collisionless matter in spherical symmetry
Ignacio Olabarrieta, Matthew W. Choptuik
We perform a numerical study of the critical regime at the threshold of black hole formation in the spherically symmetric, general relativistic collapse of collisionless matter. Th…
